The thing about robots is that once you start treating them as sapient beings capable of being characters (in the roleplaying game sense)
in their own right, they immediately get all sorts of other baggage attached to them that really should only apply to organic beings.

An example of this taken to extremes is Futurama, in which the robots are
ridiculously human to the extent that there are
unemployed robot bums, disabled robots, criminally insane robots, and an orphan robot with one useless leg and a crutch instead of an arm.

Star Wars doesn't go quite to that extreme, though when you're roleplaying it, it can just be fun to go a bit further than the source material.
